Example

[0222]These data indicate that the composition of Example 1 containing the flexibilizer (i) provided for improved flexibility (Passed) and hardness (105) when cured at room temperature for 7 days, as compared to a similar composition, Comparison 2, which failed the flexibility and had a hardness of only 84, or the commercial coating, Comparison 3, which passed the flexibility but had a hardness of only 59.

[0223]These examples are to be construed as exemplary in nature only and are not intended in any way to limit the appended claims. It is contemplated that a person having ordinary skill in the art would be able to produce obvious variations of the subject matter and disclosures herein contained that would be by reason of such ordinary skill within the literal or equitable scope of the appended claims.

Abstract

Compositions are provided which comprises an active hydrogen-containing resin, a flexibilizer and at least one curing agent. The cured compositions possess enhanced flexibility while maintaining hardness, and are highly suitable for applications such as coatings, adhesives, sealants, gaskets, industrial rubber goods, and the like.

Description

[0001]This application claims priority to Provisional U.S. Patent Application No. 61 / 928,572 dated Jan. 17, 2014, the entire contents of which are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to compositions that upon curing provide cured compositions having enhanced flexibility. These compositions are useful as coatings, adhesives, sealants and composites.[0004]2. Description of Related Art[0005]Resin compositions are useful as adhesives, sealants, composites, and especially coatings. Current high surface hardness protective coatings typically contain acrylic resins having high glass transition temperature (Tg), such as acrylic resins derived from methyl methacrylate and styrene monomers or alkoxysilane-modified acrylic resins, for example, acrylic resins incorporating (meth)acryloxyalkoxysilane, such as 3-methacryloxypropyltrialkoxysilane. While such acrylic-based coating compositio...
